This invention relates to an improved form of boat combining the qualities of high speed and small size with those of seaworthiness and relatively large capacity for carrying cargoes. Small boats are generally unseaworthy by reason of the fact that they cannot successfully ride large waves and for the further reason that only a moderately rough sea will cause sufficient pitching of the boat to raise the propeller out of the water. As the boat bottom is smooth and unbroken in its surface contour, the boat rides lightly upon the water and is quite susceptibleof violent rolling.

The present invention has for an object the provision of a relatively small boat, preferably with no decks, and almost fully enclosed, which will be extremely seaworthy and have the-ability of maintaining high speeds for a great number of hours. By virtue of its keel construction, the propeller is maintained at a considerable depth in the water and suitably formed fins are mounted so -that changes in their angularity afford changes in the height at which the boat rides through the water. By maintaining these fins under the surface while the boat is moved, there is pressure above as well as below the fins, thus preventing excessive rolling of the hull. Further objects and advantages of the invention will appear as the description proceeds, and reference will now be had to the accompanying drawings, wherein:

Figure 1 is a perspective view of a boat I built in accordance with this invention.

Figure 2 is a view in section taken in a vertical plane passing through the longitudinal axis of the boat. 7

Figure 3 is a View in section, upon a reduced scale, and taken on line 3-3 of Figure 2.

Figure 4 is a plan view showing the rudder control used on the boat.

Figure 5 is a segmental view in section showing a portion of the controlling means for the rear fins.

Figure 6 is a view in section taken on line 66 of Figure 5. V

Figure 7 is a view, partly broken away, showing the control for the rear fins.

Referring to the above drawings, a indicates the hullof a boat, in the form shown, being totally enclosed and provided with ventilatora, periscope a windows a manholes'a and exhaust ports a Obviously, the number and characterof this apparatus maybe varied to suit the requirements of various types of service and constitute no part of the present invention. The hull a is provided with a "downwardly and rearwardly extending hollow keel b, at the end of which are propellers b anda rudder 6 Above the keel Z), and adjacent the lower portion of the hulla, stationary wings '0 are formed.

These wings have stream lines and serve'as' vanes against which the spray of the boat strikes, thus tending to lift the hull from the water when the boat is under way. At such time, thewings 0' are above the water line, indicated by the dot and dash line d in Figure 2. When the boat is lying at rest,-the water line is indicated at e in Figure 2, in this position the wings a being submerged as clearly apparent from Figure 2.

Disposed on either side of the keel and adjacent the front and rear extremities thereof are lateral fins f and g, respectively. Fins f are mounted upon a shaft f which'extends transversely throughthe keel of the boat andcarries a'worm sector within the keel. A worm shaft 7 carrying a worm engaging the sectorf is turned by meansof capstan 7 This enables the angularity of the for: ward fins fto be varied and, in service, it is contemplated that these fins will be adjusted to an appropriate position for a given. setof conditionsand only varied when the conditions necessitate it. The rearward fins g are pivoted on stub shaft g which are mounted in the keel b. Rearwardly of the stub shaft a recess 6 is formed in the keel and a second stub shaft 9 mounts a crank g in the recess 6 One arm of thecrank is provided with an open slot g forreceiving a pin 9 carried by the fins g, and the other arm of the crank is provided with a pin 9 Extending rearwardly from the control room, and disposed within the'keel, are shafts 9 These shafts passthrough suitable bearings in the walls of the recesses "12 and are provided with elonme E.
